Brake fluid reservoir
Warning
Danger of accidents ಗBrake system failure.
ಥ If the brake fluid level falls below the MIN mark, this indicates a leakage in the brake system or worn-out brake linings.
Have the brake system checked in an authorized KTM workshop, and do not ride any further.
The brake fluid reservoirs of the front and rear brakes are dimensioned so that they do not need topping up with brake fluid even if the
brake linings are worn.

Brake calipers
The brake calipers of this series are "floating", which means that they are not fixed to the brake caliper support.
The lateral compensation ensures an optimal position of the brake pad in relation to the brake disc.

Checking brake discs
Warning
Danger of accidents ಗReduced braking due to worn brake discs.
ಥ Worn brake discs should be replaced immediately by an authorized KTM workshop.

Rear 3.5 ‘mm (0.14‘in)
